Re: Cannot enter command

Ok, a4 and b4 are part of the trunk trk10 and trk10 already isn't an edge-port.if an port is an member of an trunk you simple can't configure just one of the trunkports to be or not to be an edge-port. you would configere both at the same time with:no spanning-tree trk10 edge-portfrom your picture that already happend!thats all.

Re: Cannot enter command

exactly,thats what i tried to tell you..and your question why it is trk10:that isn't the default. it is configured as you can see in your sh runtrunk a4,b4 Trk10 lacpbut it is always Trkxx with xx beeing 10 in your config.hthAlex
